Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Probing quantum decoherence at Belle II and LHCb

Journal of High Energy Physics
With the advent of Belle II and the LHCb upgrade, the precision measurements of various B-Physics observables are on cards. This holds significant potential for delving into physics beyond the standard model of electroweak interactions.

Standard Model predictions for lepton flavour universality ratios of inclusive semileptonic B decays

Journal of High Energy Physics, 2022
We present Standard Model predictions for lepton flavour universality ratios of inclusive B → X(c) ℓ ν ¯ ℓ $$ \ell {\overline{\nu}}_{\ell } $$ . For the ℓ = μ, e, these ratios are very close to unity as expected.

Plate tectonics in the microscopy realm: Molecular insights into morphological variability of Peridinium willei (Peridiniales, Dinophyceae)

TAXON, Volume 75, Issue 2, April 2026.
Abstract Freshwater Peridinium willei (Peridiniaceae) is globally distributed, but reports linking its morphologies with DNA sequence data remain scarce. The taxonomy of the species, and its infraspecific taxa, remain ambiguous due to the lack of DNA sequence data for the original and type material.

Structure-dependent QED in B − → ℓ − ν ¯ γ $$ {B}^{-}\to {\ell}^{-}\overline{\nu}\left(\gamma \right) $$

Journal of High Energy Physics
Based on explicitly gauge invariant interpolating operators we compute complete next-leading order QED-corrections for leptonic decays. These are sizeable since the helicity-suppression in V-A interactions allows for structure-dependent collinear logs ...

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Robust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable isotope (δ13C‐CH4) profiles along oxygen and salinity gradients.

Approximate Mass Spectra of the Heavy Mesons Under a Coulomb Plus Logarithmic Spin‐Dependent Potential Function

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this paper, we presented an approximate analytical treatment of the Coulomb plus logarithmic potential using time‐independent perturbation theory to investigate the mass spectra of bottomonium and charmonium mesons for the low‐order quantum states.

Vector-like bottom quarks in composite Higgs models [PDF]

, 2014
Like many other models, Composite Higgs Models feature the existence of heavy vector-like quarks. Mixing effects between the Standard Model fields and the heavy states, which can be quite large in case of the top quark, imply deviations from the SM.

Probing the decay A0⟶h0Z(∗) in Two‐Higgs‐Doublet Models in the Inverted Hierarchy Scenario at the Large Hadron Collider

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
Searches are being carried out at the Large Hadron Collider (LHC) for the decay of the CP‐odd scalar (A0) in two‐Higgs‐doublet models (2HDMs) with natural flavour conservation (NFC) in the channel A0⟶h0Z, where h0 is either the discovered 125 GeV Higgs boson or is an undiscovered CP‐even scalar with a mass below 125 GeV.
